Road milling bits, also known as cold planer bits or pavement milling cutters, are specialized tools used in the process of road milling or pavement milling. This process involves using heavy machinery, typically a road mill or cold planer, to remove the upper layers of a road surface.
The bits come in various sizes and shapes depending on the specific application. Common types include:
1. Tungsten Carbide Bits: These are the most durable type, often used for milling through tough materials like concrete or asphalt. They're made from tungsten carbide, which is extremely hard and resistant to wear.
2. Polycrystalline Diamond (PCD) Bits: These bits have a layer of diamond particles bonded onto a steel core. They are used for milling softer materials and offer a balance between cutting efficiency and durability.
3. Cobalt Steel Bits: These are less durable than tungsten carbide or PCD bits but are more cost-effective. They are commonly used in less demanding a…
